# Flow cards & automations

The app exposes Flow cards so you can react to changes in your solar production.

## Triggers (When…)

| Card                           | Fires when                                                                           |
| ------------------------------ | ------------------------------------------------------------------------------------ |
| **Production started**         | Power transitions from 0 W to >0 W (sunrise, cloud passes) - exposes a `power` token |
| **Production stopped**         | Power transitions from >0 W to 0 W (sunset, cloud cover)                             |
| **Today's production changed** | The today-kWh value changes between polls                                            |
| **The power changed**          | `measure_power` changes                                                              |
| **Total energy changed**       | `meter_power` changes                                                                |
| **Frequency changed**          | `measure_frequency` changes                                                          |
| Voltage / temperature changed  | The capability changes                                                               |

## Conditions (And…)

| Card                            | True when                                 |
| ------------------------------- | ----------------------------------------- |
| **Is producing power**          | Current power > 0 W                       |
| **Power is above**              | Current power > the value you specify (W) |
| **Today's production is above** | Today's kWh > the value you specify       |

## Useful automations

**Charge the EV when the sun comes up:**

> When *Production started* on Omnik → start charging session

**Run the dishwasher only on solar power:**

> When time is 12:00 → if *Power is above 1500 W* → start dishwasher

**Notify when the system goes idle for the night:**

> When *Production stopped* on Omnik → send push "Solar finished - total today: \[meter\_power.daily] kWh"

**Frequency alarm (rare grid issues):**

> When *Frequency changed* → if *Frequency below 49.8 Hz or above 50.2 Hz* → send notification

## Tokens

The *Production started* trigger provides a `power` token (the actual wattage at the moment production started), which you can use in subsequent flow steps - useful for branching ("only charge the EV if production is at least 1 kW").
